Outspoken rock legend Roger Waters has voiced concern that Hillary Clinton is too hawkish, quipping that she might use nuclear weapons if elected president.

Waters, the former Pink Floyd member best known for the classic album “The Wall,” said he is supporting liberal insurgent Bernie Sanders as he challenges Clinton for the Democratic Party’s presidential nomination.

“I have an awful worry that she might become the first woman president (only) to drop a fucking nuclear bomb on somebody,” Waters told Rolling Stone magazine in an interview released Monday.

“There is something scarily hawkish about her,” he said.

But he said that Clinton was a better choice than Republican contenders “by a long, long way.”

Waters, who recently released a new film version of “The Wall,” lives in New York but is a British national and cannot vote in the United States.

Clinton has often been described as more willing to support military options than President Barack Obama, especially in Syria’s civil war.

The former secretary of state enjoys support from plenty of stars, with pop queen Katy Perry singing for her Saturday, although Sanders has amassed endorsements among folk veterans and indie rockers.

Waters is known for his strident condemnation of the Israeli government’s treatment of Palestinians, frequently leading to criticism of him among the Jewish state’s defenders.
